Summary
A post on Hacker News' front page describes a Show HN project that lets users type in any place and find every satellite that passed over it in the last 7 days. According to the post, the search uses SGP4 on the CelesTrak catalog and runs in the browser in about half a second. It then pulls images from those passes, including Sentinel-2, Landsat and NASA imagery. The author says the pass search cannot skip a pass and reports checking it against a brute-force method.

What happened
hey HN, i built this because i wanted to know what had actually photographed my street. type in any place and it finds every satellite that passed over it in the last 7 days (SGP4 on the CelesTrak catalog, runs in your browser in about half a second), then pulls the real Sentinel-2 / Landsat / NASA images from...
Why it matters
The project is not directly about AI chips, but it shows how public satellite catalogs and imagery archives can be searched directly in a browser. People interested in Earth observation data, or anyone who wants to know which satellites imaged a location, could find the approach useful. Next, watch whether the author's accuracy claims hold up under outside testing, since the post is a self-reported project.
